Henri, evidently suffering the pains of a long-ago death of his wife, seeks out the lakeside gay retreat as a simply place of last resort, or, one might describe it as search for a world far away “from the other side,” a part of the beach sought out by heterosexual nudists who want nothing to do with the gay boys and older men on the other side.
Michel, as the detective questioning the locals suggests, is probably more homophobic than simply interested in the thrill of the kill. Despite the graphic sex the director reveals is the tie between the two of them, even Michel suggests early on in their relationship that there will be a day in which Franck will lose interest, a day, we can only suspect, will end in his death. And there is an undertone here of a mad jealousy behind Michel’s gaze.
Yet the fact that he will not invite Franck home and even provide him with a description of how he is employed that there is something darker than even jealousy about his actions. Is he married to a woman with a family, hating himself for his sexual “indiscretions?” Does he perhaps live with a mother or father to whom it is impossible to reveal his activities?
